MACHINE FOB MOLDING BRICK.

Specification of Letters Patent No. 10,319, dated December 13,` 18.534

Be it known that I, JOHN BUTTER, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Machines for Molding Brick; and I do hereby declare that the same is ldescribed and represented in the following specification and drawings.

Many machines for molding brick have been constructed which were defective, and particularly those made with a hinged or pivoted follower to press the clay into the molds, which followers press lthe clay into the-end of the mold next to the hinge very hard, before itlls the opposite end, so that one end of the brick shrinks more in dying and burning than the other, and consequently one end is smaller than the other' making a very imperfect brick.

The object of my improvement is to remedy the above mentioned defect by pressing the clay into each end of the brick molds at the same time; which defect I have obviated by using two followers which are operated in concert with each other so as to fill and press the clay into eachend of the molds equally and simultaneously, which followers are operated by appropriate machinery either ears or levers.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and the mode of using it, referring to the before mentioned drawings in which the same letters indicate like parts in each of the gures. l Figure l, is an elevation of one end of a machine with my improvements. Fig. Q, is a section through the line a z of Fig. 3. Fig. 3, is an elevation of the front Vof the machine and Fig. 4, is a plan of the vibrating frame containing the rollers which supV port the molds when the clay is pressed into them,'and the rollers from which the full molds are .taken when they are removed from the machine. Fig. 5 is a section showing the position of the followers when they have pressed the clay into the molds.

In the accompanying drawings A A are the sills; B B back posts; C C front posts; D D rails, and E E bars which connect the post as represented and complete the frame. Upon the top of the rails D I fasten the stands F F made in the form represented and perforated for the shaft'G which has the pinions H H upon it and is operated by mediately below the followers I fasten the y box L which has a rack M M in the bottom tolcorrespond with the molds used. I; make a frame in the form represented `in Fig. 4,

with two-sides N N and bars O and P P.

This frame is provided with rollers Q Q Q which support the molds when they are unl der the box L while the clay is forced into them as the sides N N at the back end are supported by the rodBwhich passes through slots in theposts B B and is fitted into the plates S S which plates are provided with slots and bolted to the posts B B, so as to adjust the `frame' to a proper height. .The

front ends of the sides N N are supported by the rollers in the arms T T fastened to the shaft V which isl supported by boxes o o fastened to the front posts CV C; and is operated so as to vibrate the arms T T by the lever W (fastened to it as represented).V

and lower the frame and molds should any stick, stone, or other matter in the clay prevent the molds from c being shoved out readily from under the box L onto the rollers m, w, which rollers are provided with pivots which turn in the bars `P P. These rollers may be placed parallel to the sides so that the workmen may carry or move the molds containing the clay endwise, but I prefer to place them diagonally as w an, so that as the workman moves the mold endwise the rollers carry it toward him without any effort on his partso as to materially. lessen the labor of removing the molds. I make a vibrating frame to receive the empty` molds and force them under the boxV L consisting of the levers Y Y which are made in the form represented and fitted to vibrate on thev rod B. These levers are connected by the bars .e e which support` the pivots of the spherical rollers a *a upon which an empty mold is placed just in frontofthe roller b t-he pivots of which rollers turn in the upper ends of the levers Y so that whenv the levers are vibrated by the links c c which ico Y connect them to the arms Z CZ, fastened to the shaft e; which shaft turns in the boXes f fastened to the front posts C and is operated by the lever g.

The machine having been constructed and completed as above described itmay be supplied with tempered clay by setting vit under a common pug mill or otherwise; if it is set directly under the pug mill and the knives which revolve set inclined the weight of the clay, and the action of the knives will force the Clay into the molds, so as to nearly fill them; when they are placed under the rack M on the rollers Q Q Q and when the operator depresses the lever I the followers press the clay into the molds at both ends simultaneously and uniformly, and raises the lever I again; and the tender puts a case of empty molds onto the rollers a a; then by depressing the lever g the roller b forces the empty mold in and the full mold out onto the rollers x, w from whence they are taken by the olfbearers and emptied, and the molds placed upon the rollers c; a

to be forced under again and filled; and then out to be borne off as above mentioned.

I contemplate that instead of the gears which operate the followers, one, two or more levers may be used and connected by links or otherwise as may be most desirable.

I nd it a great advantage to use a movable bed of rollers as the molds are shoved in with less friction and the dirtemptied JOI-IN BUTTER.
